Embodiment 1 FIG.
FIG. 1 shows the configuration of an elevator system including an elevator electric energy display device according to an embodiment of the present invention. The cage 12 and the counterweight 13 are connected to both ends of a rope spanned over the sheave 14, and the cage 12 is moved up and down by rotating the sheave 14 by the motor 9. The power source 6, the comparator 7, the inverter 8, and the motor 9, which are elevator drive systems for raising and lowering the car 12, are based on commands from the elevator operation control means 5 a of the control command unit 5 in the control device 1 constituted by a computer. Be controlled.

  Each hall has a personal authentication unit 10 having an input unit 10b for inputting destination floor buttons 10a for performing hall call registration and destination floor registration, ID information (personal authentication information) for user personal authentication, and the like. Is provided. Thereby, the elevator call including the personal authentication information, the hall call registration floor, and the destination floor is generated. The elevator operation control means 5a is input with data indicating the state of the elevator such as the floor (position) of the cage 12 from various sensors and measuring devices (not shown) provided in the elevator. The elevator operation control means 5a controls the drive system in accordance with the above-mentioned elevator call while considering the state of the elevator from these data. A display unit 11 is provided in the basket 12.

  The drive system power amount calculation means 4 calculates the amount of power required to drive the elevator that is actually operating for each elevator call including the personal authentication information, the hall call registration floor, and the destination floor. That is, for example, the power amount of the bus S that supplies power to the motor 9 is calculated from the power of the inverter 8 that performs drive control of the motor (winding machine) 9. The power of the inverter 8 may be directly measured by a watt hour meter (not shown) or may be obtained from the control state of the elevator operation control means 5a of the control command unit 5 that performs drive control.

  For each elevator call, the facility power amount calculation means 3 is set in advance for each facility with the amount of power of an elevator facility such as lighting (not shown) in the car 12 having a small variation factor other than the drive system. Further, it is obtained by calculation from the parameters (for example, unit electric energy for each movement of the first floor of the basket 12) and the number of moving floors of the basket 12.

  The total electric energy calculation management means 5b adds the electric energy in the elevator driving system obtained by the driving electric energy calculation means 4 and the electric energy of the elevator equipment obtained by the equipment electric energy calculation means 3 for each elevator call. The total power amount is calculated, and this total power amount is accumulated for each ID information (personal authentication information) and stored in the storage unit 16 for management.

  The display control means 2 displays the total electric energy calculated together with the ID information on the display unit 11 in the car 12 when the car 12 arrives at the destination floor when the operation for each elevator call is completed, and for example, to the personal authentication unit 10 When there is a predetermined display request input including the ID information input, for example, the total power amount accumulated together with the ID information is displayed on the display unit 11 provided in the basket 12.

  Each means can obtain the state of the elevator such as which floor the cage 12 is on (position) from the elevator operation control means 5a.

  In addition, the display control unit 2 and the display unit 11 constitute a display unit, and the total power amount calculation management unit 5b and the storage unit 16 constitute a total power amount management unit.

  FIG. 2 is a schematic operation flowchart for explaining an example of the operation of the elevator power amount display device according to the present invention, and the operation will be described below. When the destination stop and ID information are input by the destination floor button 10a and the input unit 10b of the personal authentication unit 10 provided in the hall while the car is in a standby state without an elevator call (step S1), the ID is input according to the input. The elevator call with personal authentication including the information, the floor where the landing was registered, and the destination floor is registered (step S2). The elevator operation control means 5a of the control command unit 5 controls the drive system in accordance with the elevator call with personal authentication, and moves the car 12 to the destination floor via the call registration floor.

  From the elevator call registration time to the time when the car 12 arrives at the destination floor via the call registration floor, for the registered individual indicated by the ID information, the drive system power amount calculation means 4 is directly or by the elevator operation control means 5a. The power consumption of the inverter 8 is obtained from the control state, and the amount of power required for the movement of the car 12, that is, the drive of the elevator is calculated therefrom. Further, the facility power amount calculation means 3 is a parameter composed of a unit power consumption amount for each movement of the first floor of the basket 12 of each facility stored in advance. And the number of moving floors of the basket 12 during this period based on the call registration floor, the destination floor and the like. Then, when the basket 12 arrives at the destination floor, the total power amount calculation management means 5b of the control command unit 5 adds the calculated power amount required for driving the elevator and the facility power amount to total power used by the current elevator. The amount is calculated (step S3).

  The display control means 2 displays the total electric energy calculated together with the ID information on the display unit 11 in the car 12 when the car 12 arrives at the destination floor when the operation for each elevator call is completed (step S4).

  Further, the total power amount calculation management means 5b accumulates the obtained total power amount for each ID information, stores it in the storage unit 16, and manages it as a personal elevator usage amount. For example, the management is performed by accumulating the total amount of power every predetermined period (for example, one month) (step S5). Further, for example, when there is a predetermined display request input including ID information input to the personal authentication unit 10, the display control unit 2 displays the total electric energy accumulated together with the ID information on the display unit 11 in the basket 12. indicate.

  As can be seen from FIG. 1, the present invention can be constituted by a CPU peripheral circuit in the elevator control board.

It is a figure showing composition of an elevator system provided with an electric energy display device of an elevator by one embodiment of this invention. It is a rough operation | movement flowchart for demonstrating an example of operation | movement of the electric energy display apparatus of the elevator by this invention.
